In this form, the floor tool 30 has the same socket 36, and the bracket34a is secured at one end to the leaf spring 35, which is retained bythe screw 21.

The roller 3| is mounted on an arm 31a which is formed with a portion34h bent to align with the bracket 34a. The arm 31a and portion 34h'constitute a carriage which is movably mounted on the bracket 34a bymeans of a hinge 42. An adjusting element 43, on the member 34h, engagesa coacting element 44 on the bracket 34a, the latter being preferably inthe form of a tongue formed on the bracket 34a and projecting beyond thehinge 42. The adjusting element may be a screw, threaded through asleeve 45 secured to the member 34b. The coacting elements 43 and 44carry the weight of the cleaner from the bracket 34a to the rollercarriage 34h, 31a.

If the member 34h is considered as part of the bracket, then theadjustment is accomplished by varying the angular relation of the hingedmembers of` the bracket, by adjusting means spanning the hinge. Thisform of the invention also possesses the advantage that the change inadjustment does not vary the range of possible depression below normalriding position. The clearance between the hinge 42 and the spring 35 isunaiected by a change in adjustment.

, I claim as my invention:

1. In a suction cleaner, a oor tool,'a mounting including a bracketmovably attached to the 4oor tool and having a projecting portion, arollerl carrying part movably connected solely to said projectingportion, a roller journalled on -said part, and adjusting meansconnecting said part to the bracket, serving to carry the weight of thecleaner from the bracket to said part. and a spring interposed betweenthe bracket and the floor tool and resiliently carrying the weight ofthe oor tool to the bracket, whereby the floor tool may be manuallydepressedbelow any one of a series of normal riding positions determinedby the'balance between the weight of the cleaner and the tension'in saidspring when iiexed under said weight, and the position of adjustment ofsaid part.

2. In a suction cleaner, a floor tool, a pair of mountings, eachincluding a bracket movably attached to the Iioor tool one at either endof the iioor tool, projecting beyond said end, and having a projectingvertical portion,`a carriage slidable on vsaid vertical portion, aroller journalled on said carriage, and'adjusting means connecting saidcarriage to the bracket, serving to carry the weight of the cleaner fromthe bracket to the carriage, and to provide adjustment of the height ofthe carriage relative to the bracket, and a spring interposed betweenthe bracket and the floor tool and resiliently carrying the weightof thefloor tool to the bracket, whereby the oor tool may be manuallydepressed below any one of a series of normal riding positionsdetermined by the balance between the weight of the cleaner and thetension in said spring when flexed under said weight, and the positionof adjustment of said carriage.

3,. In a suctionv cleaner, a iioor tool, a roller mounting including a.bracket movably attached to" he oor tool, a'roller carrying part hingedto the bracket, for swinging movement relative to said bracket, a rollerjournalled on said part near the swinging end thereof, adjusting meansacting between, said bracket and said part, carrying the weight of thecleaner from the bracket to said part, and a spring interposed betweenthe bracket and the oor tool and resiliently carrying the weight of theoor tool to the bracket, whereby the oor tool may be manually depressedbelow any one of a series of normal riding positions determined by thebalance between the weight of the cleaner and the tension in said springwhen flexed under said weight, and the position of adjustment of saidpart.

4. In a suction cleaner, a oor tool, a mounting 10 including a bracketmovably attached to the iloor tool, a roller carrying part movablyconnected solely to the bracket, a roller journalled on said part, andadjusting means acting between said part and the bracket, serving tocarry the weight 15 of the cleaner from the bracket to said part, and aspring interposed between the bracket and the floor tool and resilientlycarrying the weight of the iloor tool to the bracket, whereby the floortool may be manually depressed below any one of 2o a series of normalriding positions determined by the balance between the weight of thecleaner and the tension in said spring when flexed under said weight,and the position of adjustment of said part.

5. In a suction cleaner, a floor tool, a mounting including a bracketone end of whichis fulcrumed, relative to the oor tool, so as to allowthe bracket to swing vertically relative to the iioor tool, a rollercarrying part movably connected to the 30 other end of the bracket,'aroller journalled on said part,iadjusting means acting between said partand the bracket, serving to carry the weight of the cleaner from thebracket to said part, and a spring interposed between the bracket andthe 35 floor tool and resiliently carrying the weight of the ilor toolto the bracket, whereby the floor tool may be manually depressed belowany one of a series ofVv normal riding positions determined by thebalance between the weight of the cleaner 4o and the tension in saidspring when flexed under said weight, and theposition of adjustment ofsaid part.

6. In a suction cleaner, a oor tool, a mounting including a bracketmovably attached to the floor 45 tool and having a projecting verticalportion, a carriage slidable on said vertical portion, a rollerjournalled on said carriage, and adjusting means connecting saidcarriage to the bracket, serving to carry the weight of the cleaner fromthe brack- 50 et to the carriage, and to provide adjustment of theheight of the carriage relative to the bracket, and a spring interposedbetween the bracket and the floor tool and resiliently carrying theweight of the Hoor tool to the bracket, whereby the floor 55 tool maybefmanually depressed below any one of a series of normal riding-positions determined by the balance between the weight of the cleanerand the tension in said spring when iexed under said weight, and theposition of adjustment of 00 said carriage.

7. In a suction cleaner, a oor tool, a mounting attached theretocomprising a bracket having a projecting non-horizontal portion, acarriage movably mounted on said portion for up and 65 down adjustmentrelative to theybracket, a roller journalled on said carriage,andadjusting means connecting said carriage to the bracket, serving tocarry the Weight of the cleaner from the bracket to the carriage, and toprovide adjustment 70 of the height of the carriage relative to thebracket, and a spring interposed between the bracket and the floor tooland resiliently carrying the weight of the floor tool to the bracket,whereby the oor tool may be manually depressed be- 1| nexed under saidweight, and the position of adjustment of aald'carriale. i

8. In a suction cleaner. a door tool, a mountin: includlns a bracket oneend of which is ful- 4 me bracket lo .wma vertically relative erumedrelative to tbe door tool. ao aato allow noot tool. a roller l other endo! the bracket, 'tor swinzlns movement relative w said bracket. a rollerl part near the end thereof means acting between said bracket and saidpart, earryinl the weight o! the cleaner from the bracket, whereby thefloor tool may be manually depressed below any one of a series o! normalridlns positions determined by the balance between the weight of thecleaner and the tension lnl said sprms and the positiva o! adjustment ofsaid part.
